1 Balanus hirsutus [taken by H.M.S. " Triton " in the Faroe Channel, 516 fathoms] and Balanus corolliformis 

 [from Station 150, 150 fathoms] are two nearly related species, corresponding in all essential respects. I must con- 

 sider them, however, as different species, because their shape is quite different, and in the second place, because the 

 tergum shows very striking differences also. . . . Balanus corolliformis is a very remarkable species, and I confess to 

 have been long in doubt whether it was a Balanus or not. The investigation of specimens of a nearly related form 

 [Balaam hirsutus'], which showed the same characteristic differences from the other species of the genus, convinced 

 me that I was right in considering them as representatives of a new section of the genus Balanus. — (Hoek, Zool. CIuxll 

 Exp., part 25, pp. 155, 6, 8.) 



2 To judge by the results obtained at Kerguelen Island in the Southern Ocean it is much rather in Antarctic than 

 in Arctic waters that the explorer who devotes himself to the search after Amphipoda may hope to find new and sur- 

 prising forms. There are, it is true, some remarkable instances in which the same species occurs both far north and 

 far south, but these are after all not very numerous. — (T. R. R. Stebbing, " The Amphipoda collected during the voyage* 

 of the Willem Barents in the Arctic Seas in the years 1880-1884," Bijdragen tot de Dierhunde, An. 17, p. 1, 1894.) 



3 A specimen of Amphilochus from the Clyde, kindly sent me by Mr David Robertson, agrees in most respects 

 with Boeck's description of his Amphilochus tenuimanus, and has also a great resemblance to the present species [Amphi- 

 lochus marionis] ; the maxillipeds in the Scotch form and in that from the Southern Ocean are remarkably alike. . . . 

 altogether the sum of the differences, added to the great distance between the localities at which the specimens ccur, 

 makes it unsafe to place the northern and southern examples in one and the same species. — (Stebbing, Zool. Chall_ 

 Exp., part 67, p. 746.)
